WCF Serialization List of objects

Below is a WCF REST service, which accepts TestEmp object. This TestEmp has a list of Jobs which I'm not able to deserialize. Below is a test application which I'm using for testing the deserialization
When I declare as public
List<TestJob> Jobs { get; set; } it works. How can I make it work with the way it is right now?
// Error
The value "System.Collections.Generic.Dictionary`2[System.String,System.Object]" is not of type "TestJob" and cannot be used in this generic collection. Parameter name: value
// Test Application Code
TestJob oj1 = new TestJob();
JOBID = "1";
JOBTITLE = "dev";
TestJob oj2 = new TestJob();
oj2.JOBID = "2";
oj2.JOBTITLE = "arch";
TestEmp oTestEmp = new TestEmp();
oTestEmp.Name = "test";
oTestEmp.Jobs = new TestJobs { oj1, oj2 };
string json = new JavaScriptSerializer().Serialize(oTestEmp);
TestEmp ap = new JavaScriptSerializer().Deserialize<TestEmp>(json); //Error
//Data Contract
[DataContract]
public class TestEmp
[DataMember]
public string Name { get; set; }
[DataMember]
public TestJobs Jobs { get; set; }
[DataContract]
public class TestJobs : List<TestJob>
[DataContract]
public class TestJob
[DataMember]
public string JOBID { get; set; }
[DataMember]
public string JOBTITLE { get; set; }

Hi,
For this scenario, it’s recommended that you use the following way to implement this:
[DataContract]
public class TestEmp
[DataMember]
public string Name { get; set; }
[DataMember]
public List<TestJob> Jobs { get; set; }

  • Need help serialize a collection object

    I have a class that's going to manage a list of paths stored as strings as "ArrayList<String> fileList = null;". I can't figure out how to serialize the fileList object. The class that contains the fileList implements Externalizable. here are the read and write functions:

    Thanks from me too Neal - this worked from me. I wan't able to consume directly from exchange because the certificate is broken. However, I was able to convince Google Chrome to let me view the /Services.wsdl and from there I could save the .wsdl and two
    .xsd files. In my case the problem lay at the top of the .wsdl file. I changed the following:
    <wsdl:types>
            <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
                <xs:import namespace="http://schemas.microsoft.com/exchange/services/2006/messages" schemaLocation="messages.xsd"/>
            </xs:schema>
    by giving the same targetNamespace as assigned in the <wsdl:definitions element, so I ended up with
    <wsdl:types>
            <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://schemas.microsoft.com/exchange/services/2006/messages">

  • Best Practice for caching global list of objects

    Here's my situation, (I'm guessing this is mostly a question about cache synchronization):
    I have a database with several tables that contain between 10-50 rows of information. The values in these tables CAN be added/edited/deleted, but this happens VERY RARELY. I have to retrieve a list of these objects VERY FREQUENTLY (sometimes all, sometimes with a simple filter) throughout the application.
    What I would like to do is to load these up at startup time and then only query the cache from then on out, managing the cache manually when necessary.
    My questions are:
    What's the best way to guarantee that I can load a list of objects into the cache and always have them there?
    In the above scenario, would I only need to synchronize the cache on add and delete? Would edits be handled automatically?
    Is it better to ditch this approach and to just cache them myself (this doesn't sound great for deploying in a cluster)?
    Ideas?

    The cache synch feature as it exists today is kind of an "all or nothing" thing. You either synch everything in your app, or nothing in your app. There isn't really any mechanism within TopLink cache synch you can exploit for more app specific cache synch.
    Keeping in mind that I haven't spent much time looking at your app and use cases, I still think that the helper class is the way to go, because it sounds like your need for refreshing is rather infrequent and very specific. I would just make use of JMS and have your app send updates.
    I.e., in some node in the cluster:
    Vector changed = new Vector();
    UnitOfWork uow= session.acquireUnitOfWork();
    MyObject mo = uow.registerObject(someObject);
    // user updates mo in a GUI
    changed.addElement(mo);
    uow.commit();
    MoHelper.broadcastChange(changed);
    Then in MoHelper:
    public void broadcast(Vector changed) {
    Hashtable classnameAndIds = new Hashtable();
    iterate over changed
    if (i.getClassname() exists in classAndIDs)
    classAndIds.get(i.getClassname()).add(i.getId());
    else {
    Vector vc = new Vector();
    vc.add(i.getId())
    classAndIds.add(i.getClassname(),vc);
    jmsTopic.send(classAndIds);
    Then in each node in the cluster you have a listener to the topic/queue:
    public void processJMSMessage(Hashtable classnameAndIds) {
    iterate over classAndIds
    Class c = Class.forname(classname);
    ReadAllQuery raq = new ReadAllQuery(c);
    raq.refreshIdentityMapResult();
    ExpressionBuilder b = new ExpressionBuilder();
    Expression exp = b.get("id").in(idsVector);
    roq.setSelectionCriteria(exp);
    session.executeQuery(roq);

    Hi,
    a list used in the singleSelectOne component does not change or set the currency in the list VO (in opposite to the navigation list). So this synchronization needs to be done programmatically. Examples of dependent list of values are available here

  • Entity object attribute with a list of objects

    Does anyone know how one sets up an entity object that has an attribute with a list of objects as the type? (assuming that's supported)
    as in:
    CREATE TYPE phones AS VARRAY(10) OF varchar2(10);
    Create table suppliers (supcode number(5),
    Company varchar2(20),
    ph phones);
    The SOA Suite in jDeveloper (new Entity Object/attributes etc) has an ARRAY that can point to REF or OBJECT. Neither work. When I try to Create DB Object later from the Entity Object I've created I get an invalid type.

    What you suggested about "validation codes on the VO" is not written on the ADF Documentation.
    I try to blindly/strictly follow best practices (particularly on Validations, using Declartive and/or built in validators) on most ADF documentation and blogs but there are many scenarios on coding some large ADF projects that I think must veer away from the best practices stated on the documentation or maybe add new rules on the documentation depending on how complex an ADF project would be.
    I religiously followed best practices stated on the documentation to use Entity and Attribute Validators when performing validations. What I did was i had created lots of Custom Validators (by implementing JboVAlidatorInterface interface) for each of the attributes on an Entity Object that need validated. So those validator is valid only for one attribute, its not reusable. And those validation codes either have reference to a ViewObject or call some PL/SQL procedure. So at some point are codes became messy.
    Ultimately the whole project became harder to manage when the codes became large. Now I am trying to refactor the whole application by separating it into project/package and I am hoping to do it with little Re-coding as possible.
    Hope to get your opinion on this one.

    Anton

  • What is Piece List, Work List and Object List

    Hi All,
    Can you please give idea about Piece List, Work List and Object List in BI.
    What are their uses?

    Hi,
    Piece lists
    You can use this request type to set up your own object lists and save them under a name of your choice.
    For more info on this go through the link below
    http://help.sap.com/saphelp_sm32/helpdata/EN/57/38e1b64eb711d182bf0000e829fbfe/content.htm
    Worklists
    Worklists are the quickest and most convenient way of accessing the objects that you need to translate. Translators can call up a worklist in SE63 once a system has been completely set up for translation.

    Object Lists
    The Object Lists tab page in transaction SLWB enables you to create and manage object lists in the Translation Planner.
    An object list should contain all objects relevant for translation. You can create object lists according to a variety of criteria

  • Best method for scrollable list of objects

    I was attempting to create a list of objects in a scrollable pane with the ScrollPane object. I am having a very hard time customizing what is actually scrolling in that pane, though. By using a custom renderer class, I am able to change what it looks like and even add objects to it, but I am having trouble passing data to those objects at creation because it is loaded through the pane object itself.
    What I would like to do is create an object with buttons on it (relative to that object) and be able to add multiple ones to a scrollable pane. I tried to figure out a way to be able to simply add my object as the item, but it seems to require a specific object. Is there any work around to this? What would be the best way of going about this?
    Thanks for any help.

  • Tag files, Lists, and object typing

    I'm passing a list of objects to a custom tag, created via a tag file.
    I can access object properties in the jsp page like this -
    <c:out value="${listOfItems[0].property}" />
    but inside the tag it doesn't work. It understands that its being passed a list and the number of items in the list but not the type of objects in the list. I think I need to declare the type of object that the list is returning but I'm unsure of th jstl way of doing this.
    advice?
    thanks

    JSTL uses introspection/reflection to call methods/access properties.
    It doesn't have to know the type of object in the list.
    How are you accessing this object in your tag file? Using EL again? That should work fine. If you use java/scriptlet code then you will need to cast the object.
    Have you declared the attribute that is being passed in? What type are you expecting? Default is String unless you specify otherwise.

  • Serialization error for object  (IDOC error 51)

    hello,
    Can Somebody help me with this??? this is what it gives me when the IDOC comes to the receiver instance (SAP R/3). The error code is 51.
    Serialization error for object 01,S,12000677 . Expected counter 000001 < 000044 in IDoc
    Message no. 5-300
    Diagnosis
    A serialization error has occurred for the HR object 01,S,12000677 that was received from the logical system E3B.
    The expected serialization counter has the value 000001. However, the serialization counter in the IDoc has the value 000044 and is therefore too big. There are therefore older IDocs with this HR object with the serialization counter values in between. These IDocs have either not yet been posted, or have been posted incorrectly.

  • Is possible to make Serializable a Connection object?

    Hi I would like to know if is possible to make Serializable a Connection Object, I would like to save the Connection object into a text file so other class can read it and execute a proper query. If is possible how can I do it?.
    Thanks.

    Actually, if a class isn't already Serializable, you can't make it become Serializable reliably. Consider the following case:
    class A
        int x = 0;
        public void setX(int new_x) { x = new_x; }
        public int getX() { return x; }
    class B extends A implements Serializable
        int y = 0;
        public void setY(int new_y) { y = new_y; }
        public int getY() { return y; }
    public static void main(String arg[]) throws Exception
        B b = new B();
        b.setX(10);
        b.setY(12);
        someObjectOutputStream.writeObject(b);
    }The problem with this is that the implementation of Serializable by class B does not affect class A. In the above example, the ObjectInputStream that obtains the instance of B will have a y value of 12, but an x value of 0 (not 10).
    Thus, unless the Connection object implemented Serializable to begin with, it can't become Serializable. And, as the above post has described, the implementers of the Connection object would not make it Serializable as the local Connection object uses underlying O/S resources which cannot simply be transformed into a byte array.

  • Changing focus line in List View object?

    Hi -
    I have an list view object on my dashboard that displays about 50 lines of data, with the very first line being a total line. You can drill-into the any one item on the list view to see detail in another chart. The content of the list view is updated when the date range is change from current month to previous month.
    My question is this: if I select the 5th line item in the list view then change the date range, the list view retains the focus on the 5th line even after it is updated - so is it possible to force the list view to change the focus to the 1st line everytime the date range changes?
    I am guessing no because I see nothing in the properties of the list view that allows you to control focus.
    Thanks in Advance!

    Melissa,
    No there is no option as such in the component. May be you can use the Reset button component.
